Players' struggles on the Champions Tour are visible and often audible. This is the 50-and-over bunch, after all.
There are muffled winces and groans at placing and picking up a tee or retrieving a made putt. Knees creak, hips pop and necks crack.
Two years ago, Hal Sutton hit his second shot into a back-left bunker on the 14th hole at TPC Twin Cities during the 3M Championship. He addressed the shot then backed off several times.
The sound of bone-on-bone in his hip was loud enough to interrupt his pre-shot routine.
"That's probably when I knew it was time," Sutton said. "It hurt bad. All the time. It's one thing to hurt all day long, but if you hurt all night long too you don't rest. Nothing fixed it."
He opted for hip replacement three months later, then had the other side done the following year.
Sutton joins a long list on the Champions Tour who face long waits and invasive pat-downs at airports thanks to metal where there was once bone.
For the 1983 PGA Championship winner, it's a small price to pay to be on the road back to high-caliber golf.
